Handling The Lookup Values?
Mar 14, 2012i am using the LookupEdit control from DevExpress fairly heavily in my projects. It is like a combobox, but it is bound to a datasource and can display multiple columns from the datasource. A single column is identified as the "value" column and a single column is identified as the "Display" column.
I use the LookupEdit control on my forms to give users a pick-list of appropriate values for a particulat database field. Each field has its own table in the database holding said values, commonly referred to as a lookup table, and each lookup table is used as the datasource for each paired LookupEdit control. Of course when a form is being filled-in by the user this works great. And it works good when the user opens a saved record into the form and I set the EditValue of the LookupEdit based on the value stored in the database. Pretty basic stuff right?
Now here is the problem... Let's say a lookup value is no longer an appropriate entry and so it is removed from the lookup table. Say I sell cars and one of the fields in the Cars table is Color. And I have a lookup table called CarColors and the selections are: Black, White, Red, and Silver. Now let's say we sold some Red cars in the past, but now we no longer carry Red as an option and we probably never will. So I remove "Red" from my lookup table, and now when I load an old Order into my form the LookupEdit for Car Color value now shows NULL. What is the best way to handle this situation? ProcessNewValue? Set NullText property? Use a bit field in my lookup table for IsActive, and set to FALSE for Red instead of deleting it?
Obviuosly I want to retain the historical values while maintaining a currently valid lookup list. And I know this question goes deeper as there are probably database design considerations like whether or not to put a constraint on the foreign key relationship between the lookup and child table, etc... I should also mentioin I am using LookupEdit control rather than a ComboBox becasue a lot of my lookups have other information like Description, Sort Order, or are coded and thus require a multiple column display.
Pass Multiple Values And Return Multiple Values?
Jun 10, 2011When I click on button1, employee_id and P values need to be transferred from button1_click to Cal_Category13() and go through all the calculation. After the calculation, udtnew.X and udtnew.MTD values need to be transferred back to button1_Click
I've no problem to return multiple values Cal_Category13().MTD and Cal_Category13().X from Cal_Category13() to button1_Click but i've no idea how to transfer employee_id and p values from button1_click to Cal_Category13().

Providing Help Documentation In .NET?
Apr 26, 2010I have written up troubleshooting documents for my project and would like them included in my program. I remember in VB6 there was a very easy way to do this with a control, where it already has the help document tree set up on the left and you just set it to point to certain files.
Does something like this exist for .NET? I am aware of the HelpProvider control but as far as I know this just puts in tooltips and opens documents on a button press?
Exclude Multiple Values In Sum Depending On Values In 2 Columns In SSRS 2005?
Apr 21, 2009I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?

Is This A Secure Method Of Providing Service For Database Applications
May 10, 2012WinFormsApp Login passes information to .php (server based) Login (provided credentials are correct) to DB to retrieve Decryption Key. WinFormsApp then uses Decryption key on Hardcoded encrypted connection string and renders application usable.This would then eliminate the necessity to encrypt/decrypt a connection string at runtime, virtually rendering any unauthorized person with a useless software.

NetBios Name Resolution / DNS Lookup In VBA
Jul 16, 2009I have an Access 2003/2007 application that pulls computer names from my network along with their last know TCPIP address. This data is created by another application. I am trying to use the IP Adresses to install software via a push application that accepts a list of IP Addresses.My app has a history table of every comuter that has been checked to see if the software is installed. I use the Fully Qualified Domain Name to make this verification. I then populate my text file with the IP address of the computers that have not been installed.This all works well if the last know IP address is still valid for that computer.What I am trying to find is a function that I can pass the FQDN to and have it do a NetBios lookup to return the current IP Address from our DNS Servers so I can be sure that the IP addresses I am populating the text file with match the FQDNs of the computers I am trying to push the software to.I found some info on System.Managment.dll. For some reason Access will not let me add it to my library references.Does anyone know of a standard library function I can use to achive this.[code]

IS there anyway to accomplish this in SSIS with a lookup? Or is there a better way?
